Appropriate marking not only enables proper use, but also assists in proper
storage. The following information generally applies to all cylinders:
- Cylinders shall be kept away from radiators and other sources of heat
- Inside of buildings, cylinders shall be stored in a well-protected, well-ventilated, dry
location, at least 20 feet (6.1 m) from highly combustible materials. Cylinders should be
stored in assigned places away from elevators, stairs, or gangways, or other areas where
they might be knocked over or damaged by passing or falling objects, or subject to
tampering
- Empty cylinders shall have their valves closed
- Valve protection caps, where the cylinder is designed to accept a cap, shall always be
in place, hand-tight, except when cylinders are in use or connected for use. The valve
protection cap is designed to take the blow in case the cylinder falls.
Additional requirements exist for the storage of fuel gas and
oxygen cylinders. Click on the appropriate term for more information.
